Plain Guide Rails Heel No Groove

Plain linear guide rails are commonly used in sliding and undercut plate assemblies where stable motion and repeatable alignment are critical. This heel-profile variant (not featuring a heel oil groove) is designed to support smooth, consistent guidance while helping keep the contact area cleaner under typical shop conditions.

• Industrial motion slide plates: In linear slide mechanisms, the non-groove heel form supports controlled lubrication behavior and reduces the risk of contaminants migrating to the rail interface, improving long-term positional stability.
• Automated handling fixtures & tooling: When guide plates must maintain parallel motion during repeated cycles, the 100 mm fixed rail length option simplifies layout and helps ensure predictable mating geometry with the corresponding support components.
• Machine tool accessory assemblies: The stable heel contact suits applications that require uniform sliding resistance and reliable tracking over multiple strokes, especially when paired with appropriate mounting hole patterns for rigid attachment.

Engineers typically select this variant for its heel no-groove geometry and fixed length, enabling easier design standardization in guide-rail subassemblies.

This guide rail series is offered in HPM2T or SKS3 tool steels, with an optional oil groove versus non-oil groove configuration. While the product data specifies material choice, it does not list exact heat-treatment condition or measured hardness, so users should confirm the supplied hardness level with the steel certificate for the specific batch.

• HPM2T: Commonly chosen when higher wear resistance and dimensional stability under sliding conditions are prioritized. The trade-off is that optimized toughness/ductility depends strongly on the final quench & temper or equivalent heat-treatment schedule.
• SKS3: A practical choice for good machining and wear performance in guide components where balanced toughness is desired. Final performance depends on the quenched & tempered condition or any subsequent surface treatments.

Oil groove vs non-oil groove: An oil groove can support lubrication distribution, while the heel no-groove design focuses on maintaining clean, consistent contact behavior.

Selection starts with matching the fixed rail length and the required rail cross-section. This product specifies L (rail length) = 35 ~ 190 mm in the series range, and the meta description indicates a fixed 100 mm rail length variant for this configuration—confirm the ordering option you need for your layout.

• Thickness (T): choose within 10 ~ 30 mm to match the space available and stiffness requirements.
• Width (W): select within 10 ~ 40 mm based on contact area and alignment with mating guide components.
• Mounting holes: pick 2, 3, or 4 hole versions, then match the bolt hole pitch steps to your plate pattern using A = 6 ~ 10.5 mm, B = 16 ~ 31.5 mm, C = 26 ~ 52.5 mm, and the listed D pitch ranges (e.g., 36 ~ 94, 41.5 ~ 143, 46.5 ~ 192.5, 57 ~ 191, 67.5 ~ 189.5, 73.5 ~ 189.5 depending on configuration).

Use mechanical drawings to ensure fit: maintain proper clearance for bolts and align the rail heel profile with the mating guide surface to avoid binding during travel. This series provides configurable hole-pattern and material options; thickness/width must be selected to your cavity/core-like mounting geometry.
